The Mets believe that the 23-year-old Montero is ready for this challenge.

"It's a very similar thing that we talked about with Ruben Tejada a few years ago," Mets manager Terry Collins said, referring to his shortstop. "I think his maturity is beyond his years as a pitcher. This guy has a feel for pitching. He knows when to pitch inside. He's not afraid to pitch inside. He's a strike thrower with all his stuff. The Dominican players nicknamed him 'Little Pedro' because he's got a feel for it. Those are big statements. I don't think he's going to be intimidated. Obviously he might be a little anxious, but I think once he gets out there, he's going to be who he is, because that's his mentality."

Montero arrived in New York on Tuesday after being promoted from Triple-A Las Vegas, where he was 4-1 with a 3.67 ERA in eight starts. Montero is set to become just the second Met to make his Major League debut during the Subway Series, joining Jaime Cerda (2002), according to MLB.com.

"That's really what I work hard for and train for, because it could happen at any moment," Montero said. "I'm really glad the time is here."

Tanaka, who has started his big league career with a perfect 5-0 record through seven starts, may be the Yankees' best bet to break up the Mets' winning party.

"No pressure; nothing changes what I need to do," Tanaka said through an interpreter. "I'm just going out there and doing my thing, so no pressure on me."
